So far the biggest problems I've encountered are the lack of an "underline" icon in the "reply" window, and my inability to access the icon for creating internet links as text. The "quote" function failed me on one occasion, but I closed the window and reopened it and it worked fine.

Couldn't make the "quote message" function work at all today. However, when I replied to a message after clicking on the "quote" icon, I did get the "underline" icon and the "URL as text" icons. They still don't show up as part of the normal "Quick Reply" or "Full Version" windows.
